Referring to the drawing .in detail, wherein like numerals indicate likeelements, there is shown in FIGURE 1 a light fixture designated-generally as 10.

The light lixture 10 is a type which is adapted to be mounted within arecess or the like. Fixture 10 includes a housing or lamp carryingmember 12 having a bezel 14 which is adapted to .be flush with theceiling or other supporting surface.

The bezel 14 includes angle plate mem-bers 16, 18, 20 and 22 xedlysecured thereto and spaced radially outwardly from the inner peripheralsurface of the bezel 14. The bezel 14 has a centrally exposed apertureover which lies a light diffusing member 24. The periphery lof member 24is supported by the inner periphery of the bezel 14.

The housing 12 is provided with walls for-ming a rectangle which islanger than the rectangle formed by the upstanding portion of themembers 16, 18, 20 and 22. Thus, the last-mentioned upstanding portionsare adapted t-o enter into the housing 12 in lthe assembled dispositionof Ithe housing and bezel. Housing 12 includes oppositely disposed sidewalls 26 and 28.

Each of the walls 26 and 28 is structurally interrelated with the bezel14 by means of a diffuser holding means 36. Since each of the diffuserholding means 36 is identical, only one such means and its structuralinterrelationship with a side wall of housing 12 and bezel 14 will bedescribed in detail.

A bracket member 30 `having an inwardly exten-ding flange portion issecured to the side wall 28 in any convenient manner. The inwardlyextending portion is provided with spaced notches 32 and 34. Thediffuser holding means 36 includes a torsion spring 5t) having legs 40and 42. Leg 40 terminates in a leg extension 44.

Extension 44 is substantially at right angles to the leg 40. Extension-44 has a gener-ally V-shaped terminal 46. Leg 42 has a leg extension 48disposed substantially at right angles to the -leg 42. Extension 48 isadapted to interlock with the terminal 46 as shown more clearly inFIGURE 7.

The torsion spring 50 of each diffuser holding means is coupled to thebezel 14 in any suitable manner. Thus, :a suitable fastener such as arivet 52 may extend through the torsion spr-ing 50 joining the legs 40and 42 and secure the spring to the upstanding portion of the angle 3worker having to search for -blind holes through which the legs willextend. When the bezel 14 is coupled to the housing 12 in its closeddisposition, the diff-user holding means 36 assumes the positionillustrated in FIG- URE 8.

When it is desired to have access to the interior of the hous-ing 12 formaintenance or replacing a burnt out bulb, one need yonly pull down onthe bezel 14 thereby causing the legs 40 and 42 to m-ove towards eachother until the leg extension 48 is interlocked with the V-shapedterminal 46. The provision of an interlock between :the tree ends of thelegs 40 and 42 prevents inadvertent pulling on the bezel 14 with such aforce as to physically separate the holding means 36 from the housing12. When the bezel 14 is in the open disposition as illustrated inFIGURES l and 7, it may be rotated, through a limited angle, :about anaxis extending through the longitudinal axis of the spring 50 therebyincreasing the space from which Iones hand may extend to replace 4a bulbor perform any maintenance function.

As discussed previously, any accidental engagement against the bezel 14will cause the legs 4G and 42 to collapse towards each other thereby-causing the bezel 14 to slide down away from the housing or lampcarrying member 12. This is usual-ly due to a certain jarring of thebezel. In :order to prevent such accidental disengagement, each of theleg members 40, 42 intermediate their ends is roughened to form aplurality of crimps such as 54 and 56 which may comprise notches,serrations, or indentations. Each series Iof crimps extends along eachleg member. In the closed disposition of the bezel 14, the resiliency ofthe legs 40 and 42 will force the crimps 54 and 56 to form a seat andbite into the adjoining edges of the bracket 38 surrounding the notches32 and 34. This added seated engagement of the spring 50 will precludeaccidental disengagement of the bezel 14 from the housing 12. That is,if a certain jarring force is imparted to the bezel 14, and the legs 40,42 are caused to move towards each other momentarily, the edges of thebracket 30 surrounding the notches 32 and 34 will bind against thecnimps 54and 56 when the bezel 14 attempts to pull away from the housing12. If the jarring force is great enough, the bezel 14 may slipslightly, but since the crim-ps are formed in a series on each leg, thespring 50 will quickly rebind :against the adjoining edges of thebracket 30. That is, even if the slippage of the bezel 14 is'initiated,the eiect of the crimps is to prevent any prolonged movement since theypresent a `roughened engaging surface to the bracket rather than asmooth surface.

Referring now specifically to FIGURES 9 and 10, a diffuser holding meansgenerally designated by the numeral 146 may .be used in lieu of thediffuser holding means 36 in conjunction with the bezel 14 illustratedin FIGURE l.

The diffuser holding means 146 includes a torsion spring 147 having legs148 and 150 and a U-sha-ped loop `portion 152. As illustrated moreclearly in FIGURE 9, the loop portion 152 is shorter in length than thelegs 148 land 150. In the closed disposition of the bezel 14 withrespect rto the housing 12, the bight portion of the loop portion 152 isspaced further from the torsion spring 147 than the vertical distancebetween the free ends of the legs 148 and 150 :and the torsion spring147.

The bight portion of the loop portion 152 is adapted to extend around alug 154 centrally located and extending perpendicular from the bracket36, land limits the extent to which the bezel 14 can be reciprocatedwith respect to the housing 12. As shown in FIGURES 9 and 10, thetorsion lspring 58 is coupled to the upright p0rtion of the member 20 bymeans of .a rivet 156, if desired or any other suitable means.

The legs 148 and 150 of the diluser holding means 146 are each formedwith a series of crimps 158 which function in the same manner as thecrimps 54 and 56 4 disclosed in conjunction with the diffuser holdingmeans 36.

When it is desired to assemble the bezel 14 to the housing 12, theWorker will first couple the loop portion 152 of each diffuser holdingmeans 146 to its respective lug 43. Thereafter, the housing 12 willsupport the weight of the bezel 14 and the light diffusing member 24.Thus, the workers hands will be free to compress the legs 148 and 150until they lsnap into the notches 32 and 34, respectively. Thus, thediiiuser holding means 146 does not rely on the terminal portions of thelegs 148 and 156 to act as limit stops. The bezel 14 may then be lpushedupwardly until the crimped portions 158 on each of 'the leg members isengaged on the edges of the bracket 3) adjoining the notches 32 and 34.In all other respects, the use of the diffuser holding means 146 iscomparable to the diiuser holding means 36.

Referring now to FIGURES ll and 12, there is illustrated yet anotherembodiment of a diffuser holding means generally designated by thenumeral 160 which may be used with the recess mounted light iixture 10of FIGURE 1. The diffuser holding means 160 can be constructed :and`oriented with respect to the bezel 14 and lamp carrying member 12 in amanner which is simpler and cheaper than the diffuser holding means 36and 146.

The diffuser holding means 160 includes a U-shaped loop 162 similar toloop 152. The free ends of the U-shaped loop 162 are formed intotraction springs 164 and 166. A spring leg is integral with one side ofthe traction spring 164. A spring leg 168 is integral with one side ofthe traction spring 166.

When the bezel 14 and housing 12 are spaced from one another asillustrated in FIGURE l1, it will be noted that the length of theU-shaped loop 162 is slightly less than the length of the spring legs168 and 170. The bight of the U-shaped loop 162 overlies the flug 43 inthe open disposition of the housing 12 and bezel 14 as is the case withthe diffuser holding means 146. A pair of spaced tabs 174 and 176 arestruck from the upstanding portion of member 26, Each of the tractionsprings 164 and 166 extends through one of the tabs 174 and 176.

When assembling bezel 14 to the housing 12, the worker will first couplea diffuser holding means 160 to opposite sides of the bezel 14. Suchcoupling may be effected by threading spring leg 170 through tab 174 andspring leg 168 through tab 176. Since the diffuser holding means ispreferably made from spring wire, a deformed spring holder means damagedduring transit or storage may be discarded. Hence, the entire bezel and/or lamp carrying member need not be discarded when the diffuser holdingmeans has been damaged.

Thereafter, the worker will support the bezel 14 with one hand andcouple each of the diluser holding means 160 to the housing 12 byplacing the bight of the U-shaped -loop 162 over the juxtaposed lug 43.When this has been accomplished, the housing 12 will support the weightof the bezel 14 and the light diffusing member 24. Thus, the workershands will be free to compress the legs 168 and 170 until they snap intothe notches 32 and 34, respectively. Each of the legs 168 and 170 areprovided with a series of crimps 172 which will function in theidentical manner Iand for the identical purpose as the crimps 158, 54and 56. In all other respects, the opera tion of the diluser holdingmeans 160 is similar to the diuser holding means 146. It should be notedthat movement of the bezel 14 with respect to the housing 12 is alsolaccomplished with less resistance due to the fact that the legs 168,170 las well as the U-shaped loop 162 lie in the same plane. Thus, anytwisting effect which will cause a binding action between the diffuserholding means and housing 12 will be eliminated. The assembleddisposition of the housing 12 and bezel 14 is accomplished by merelypushing upwardly on the bezel 14 until the components assume thedisposition illustrated in FIG- URE 12.

Referring now to FIGURE 2, there is illustrated another embodiment ofthe present invention wherein the light fixture is the surface mountedfixture designated generally by the numeral 60. Fixture 60 includes atray or lamp carrying -member 62 structurally interrelated with a bezeldesignated generally as 64 by diffuser holding means 66. Diffuserholding means 66 is preferably lidentical with the diffuser holdingmeans 36, and therefore need not be described in detail.

The tray or lamp carrying member 62 may be flat sheet metal or the likehaving upstanding peripheral flanges 68, 70, 72 and 74. Tray 62 isprovided with an aperture 76 adjacent flange 68 and an -aperture 78adjacent flange 72. A portion of' each diffuser holding means 66 extendsthrough the aperture so that the torsion spring is above the tray 62 forfacilitating coupling of the torsion spring to one of the flanges 68 and78. Each of the flanges 68 and 78 is provided with a struck-out portion.The member 80 comprises a hook having a bight portion spacedsufliciently from the plane of the upstanding peripheral flange 68 sothat at least one coil of spring 50 extends therebetween and may becoupled thereto. The smplicity of this -means for coupling the spring 50to the tray 62 eliminates manufacturing steps, necessity formanufacturing equipment such as welders or riveters, and enables thediffuser holding means 66 to be readily replaced when desired. Thus, ifthe diffuser holding means 66 is bent or broken, it may be readilyreplaced without the necessity for production equipment.

The bezel 64 is provided with side walls 82, 84, 86 and 88. Each of theside walls is provided at its upper edge with a turned-over portionwhich terminates in an inwardly directed flange. Thus, side wall 70 isprovided at its upper edge with a portion turned back on itself and aninwardly extending flange 90. Side wall 86 is similarly provided with aflange 92. The flanges 90 and 92 are provided with notches whichcooperate with the leg of the diffuser holding means 66 in the samemanner as notches 32 and 34 cooperate with the diffuser holding means36, 146, and 160.

Each of the side walls of the bezel 64 are provided at their lower edgewith an inturned flange. Thus, Wall 86 is provided with a flange 96. Theflanges at the lower edge of each of the walls of the bezel 64 provide asupporting surface for a light diffuser member 94.

The bezel 64 may be formed from an elongated member having a lengthcorresponding to the combined lengths of the walls 82, 84, 86 and `88.Thereafter, the strip may be bent to form a rectangular bezel asillustrated with means being provided at one of the corners tofacilitate joining the free ends in any convenient manner well-known tothose skilled in the art to which the present invention pertains. Itwill be noted that the flanges such as flange 90 are cutaway at theirends so as not to be integral with the corresponding flange on the otherside walls. Thus, flange 90 is provided with a cut 98. A- similar cutshould be provided in the flanges such as flange 92. These cuts arepreferably at 45 angle with respect to the leading edge of the flangesso that they mate with cooperating flanges on the other side walls. Thefixture 60 is utilized in the same manner as described above withrespect to the fixture 10. Reference should be made to FIGURES 13 and 14illustrating respectively, the open and closed dispositions of the bezelwith respect to the lamp carrying member 62.

lReferring now specifically to FIGURES 15 and 16, it will be seen thatthe diffuser holding means 180, identical to the diffuser holding means146 may be used in the lighting fixture 60. FIGURE 15 illustrates theopen disposition of the bezel and FIGURE 16 illustrates the closeddisposition of the bezel. The diffuser holding means 180 performs thesame function in an identical manner as the diffuser holding means 146and accordingly, a further explanation is not thought necessary.

Referring now specifically to FIGURES 17 and 18, a diffuser holdingmeans 178, identical in every respect to the diffuser holding means 160,is shown in the manner in which it would be used with the lightingfixture 60. The diffuser holding means 178 is identical in every respectand functions as the diffuser holding means 160. FIGURE 17 illustratest-he open disposition of the bezel .and FIGURE 18 illustrates the closeddisposition of the bezel. No further explanation is deemed to benecessary as it would yreadily be apparent to one skilled in the art asto how the structure of FIGURES 17 and 18 will be used.

Referring now to FIGURES 3-6, a more or less conventional suspendedceiling fixture is generally designated by the numeral 100. The fixturecomprises a ceiling plate 102, rods 104, and -a base plate 106 mountingthe various sockets 108, which accommodate light bulbs 110. A supportdisc 112 is adapted to be connected to a housing or lamp shade 132surrounding the bulbs 110.

The fixture 1-00 further includes a bezel 116 having an inturned flange117 on which seats a light diffusing member 114. Extending -radiallyinwardly from opposite diametrical portions of the bezel 116 are a pairof arms 134 and 136 for supporting the torsion spring 144 of a diffuserholding means 118. The arms 134 and 136 extend through the spring 144and provide a convenient means on which the spring 144 seats. In theevent that the diffuser holder means 118 is damaged, it may readily belremoved .from the bezel and replaced.

Each of the diffuser holding means 118 includes a pair of legs 120 and122 extending outward from the torsion spring 144 at a large angle. Eachof the legs includes an outwardly extending stop such as 124 bent atsubstantially right angles to the ends of each of the legs. Further,extending along each of the legs is a series of crimps such as 130.

The support disc 112 is preferably formed with two pairs of nearlydiametrically opposed elongated slots 126, 128 adjacent to each other.The legs 120 and 122 of each torsion spring are pressed together tointroduce them into said adjacent slots. As the bezel 116 is movedupwardly as far as it will go toward the support plate 112, the legs 120and 122 are urged apart by the coils of the torsion spring 144 forengagement with the outer ends of the respective slots 126, 128. Whenthe bezel is in its closed disposition as illustrated in FIG. 5, thecrimps 130 will frictionally bind and catch the edges of the slots 126and 128, whereby the bezel 116 will become securely retained inoperative position to prevent it from sliding downwardly into the opendisposition as illustrated in FIGURE 6 by the application of a jarringforce on the bezel.

The upwardly extending legs 120 and 122 of the diffuser holding means118 are concealed by the lamp shade 132.

For access, bezel 116 may readily be pulled downward. In this downwardmovement, as will readily be seen in FIGURE 6, the stops 124 limit thedownward movement so that the bezel and its light diffusing member 114remain on and will not become physically separated from the fixture. Inthe open disposition of the bezel as illustrated in FIGURE 6, the workermay readily replace the diffuser 114 or perform other servicing.Thereafter, the bezel 116 with its diffusing member 114 are simplypushed back into position.

The present invention may be embodied in other specific forms withoutdeparting from the spirit or essential attributes thereof and,accordingly, reference should be made to the appended claims, ratherthan to the foregoing specification as indicating the scope of theinvention.
